END WALL FOR RATLWAY CE RS,

Application filed March 8, 192 (5.

Reference is had to the accompanying drawings, which illustrate thepreferred form ofthe invention, though it is to be understood that theinvention is not limited mule exact details of cons ruction shown anddescribed, as it is.oi' vious that various thereof within the scope ofthe claims will occur; to persons skilled in the ap i invention relatesto the construction ot a railway car having an ehd wall made ofjone ormore metallic plates secured to-- gether and reiniorced withstiiieningand bracing. members. While efforts are made o to block the lading inthe car, the shocks caused by the heavy locomotives, the emergencyairbrake, and the classification hump tear the lading away from itsmoorings and throw it against the end of the our, and the lateralweavingof the car throws it against the side oiv the car. The inventionis readily adaptable to box, gondola and other types ot' railway cars. 4

7 One of the objects of the invention is to provide afwall element whichhas great strength to resistthe torsional and weaving stresses whichexist in. a railway car, when moving in service. These stresses arecausedfby the Iinertiaof the roof and superstructure" when the train is.suddenly stopped; rough or uneven track; the superelevation. of thetrack on curves; the. lateral inertia in rounding curves; eccentricthrust due. to the lading being secured to one side of the car; the carsbeing cornered; the use of push pole pockets, etc. Such stresses rackand distort the superstructure which decreases the life of, the car, andalso causes the. car to leak grain, sand, and other'suchmaterial.Furthermore, such stresses cause leaky roofs and lealry and inoperativeside and end doors.

The tendency of present designs of all metal end walls to bulge isresisted partially by the corrugations, stiffening members or whatevermeans have been provided to transmit such stresses to the side wall orframe members of the car. Such tendency is also resisted by the cornerpost of the car ctin as a vertical beam supported at its top and bottomand sustaining a horizontal load; in other words, the bulging of the endwould pull the opposite corner posts toward each other. This bulgingalso tends e ia e. 31 5 to pull the end (or side) platedownwardlv andthe end (orside) sill upwardly. I in rny construction the end wall isresiliently or. yielding ly attached to the frame members ofihe car 'andthe stiffening means terini nete within this resilient arrangement andare not attached to) the car namefmm hers. "With' such a constructionthe strains and d stortions of a bulging: end wall are not. transmittedto the l ia ne iiiembers of the'czir. The stranger a bulging end Wallare concentratedin the end Ran" itself and not distributed to other:parts'ijof. the car. thus reducing the cost to 'repair the andIsimplifving tlie r eplacemeht' of the end we r.

Another objectof the; invention is to attach an end wall to a. railway,car so. that its distortion, due to bulging; is not transmitted to the:nljaceI1t-. fra1nemembers 'bt the car.

Another objectis to form a depressed panel in a metallic end wall which.reinforces and strengthens the end; wallf andet 'the same tlmeiprovidesa bearing' surface" 61 lining b oards. I i

In the: drawings:

The usual railway box car is provided with an end sill 1; end plate 2and corner posts 3 whi ch constitute' a rectangular frame for the endwall; The, bot'tbnifof the end plate '2 sometimes conforms to theqslopes A of the root. In a gondola car'the' ,top. 'end' chord is a framemember. i z

My end wall comprises one or more metal- 110 plates 4i-5 connectedtogether and secured to the above mentioned end frame. The end wall hasa central portion 6 offset (preferably depressed inwardly toward thecar) so as to form a continuous web 7 adacent the end frame. Thiscontinuous web, however, is not secured to the end frame so that if theend wall bulges its distortion is not transmitted to the end framemembers.

The oilset central portion 6 of the end Wall is reinforced by aplurality of transverse beams lfl ll which cross the cencured to thecontinuous web.

tral portion and are preferably the same depth as the continuous web 7.These beams terminate adjacent the opposite portions of the web and arenot secured to the adjacent frame member so that any distortion ordeflection of any of these beams is not transmitted to the end frame ofthe car.

In the preferred form there are a plurality of plates connected onhorizontal lines forming the end wall with a central reinforcing beam10, as shown in Fig. 1.

It is desirable toline metallic end walls with wooden boards to preventthe moisture on the inside of the metallic plate. due to condensation,from coming in contact with the lading; furthermore, such Wooden liningboards act as cushions to absorb minor shocks caused by the shifting ofthe lading. In order to line my end wall I .provide wooden nailingstrips 20 positioned between the con tinuous web and the adjacent framememher, which nailing strip is preferably secured to the end wall eitherat the marginal portion, as shown in Fig. 3, or it may be se- The liningboards 21 are preferably positioned normal to the direction of thereinforcing beams and are nailed or otherwise secured to the nailingblocks and are also preferably secured to the central beam by bolts 22or other means, therefore, when the end bulges the lining boards simplybend or deflect with it. The lining boards are in contact with theofiset portion of the metallic plate so that they are backed up orsupported over substantially the entire area of'the end wall.

In Fig. 4 the plates 30 31 are connected along" horizontal lines and thetransverse beams 82 are also positioned horizontally.

I claim: I

1. In a'railway car having "four members constituting a substantiallyrectangular frame for an end wall; the combination of an end wallsecured to said frame having an offset central portion forming acontinuous webwith portions-parallel to and adjacent each of saidmembers but not secured thereto, and a plurality oftransverse beamscross ing said offset portion terminating adjacent the o 'positeportions of the web.

2. l n a railway car having four members constituting a substantiallyrectangular frame for an end wall; the combination of an end wallsecured to said frame having an offset central portion forming acontinuous Web with portions parallel to and adjacent each of saidmembers but not secured thereto, and a plurality-of transverse beamscrossing said offset portion terminating adjacent the opposite portionsof the web, which beams are substantially the same depth as the web.

3.
